Primary Outcome Measures
NameTimeMethod
Incidence and severity of treatment-emergent adverse events (TEAEs) as assessed per NCI CTCAE v5.0 criteria;Dose Limiting Toxicities to determine a maximum tolerated dose and schedule of RP-1664 based on safety and tolerability as measured by CTCAE v5.0, pharmacokinetic parameters, pharmacodynamic readouts and efficacy data per RECIST or INRC criteria
Secondary Outcome Measures
NameTimeMethod
To assess the PK parameters of RP-1664 in the fed and fasted states by measurement of plasma concentrations of RP-1664 with calculation of maximum observed plasma concentration (Cmax).;To assess the preliminary anti-tumor activity of RP-1664 in participants with molecularly selected advanced solid tumors treated at pharmacologically active dose ranges. Anti-tumor activity will be measured by ORR according to RECIST 1.1 and INRC.
